When to replace the oxygen sensor in a Toyota Camry?
So if you want to get back to descent gas mileage (without spending more then the cost of the extra gas used this week), use these following instructions to replace the air/fuel (oxygen) sensor in your Toyota Camry.
Where are the oxygen sensors on a car?
Oxygen sensors are located before and after the catalytic converter. A vehicle may have two to five oxygen sensors, and sometimes even more. How does the oxygen sensor work? The information from the oxygen sensor is used by the engine’s computer to help determine how much fuel is needed so that the engine will run efficiently.
Can a Camry service engine sensor go bad?
Your Camry can exhibit symptoms when the Oxygen sensor has gone bad. Or, it may exhibit none at all. Often enough, the only sign of the problem at all is the service engine soon light being on. The good news is, if you end up discovering that the oxygen sensor is bad, they really aren’t that expensive to replace.

How to test and replace O2 oxygen sensor?
Unplug the sensor. Connect your multimeter to read the DC voltage on the harness plug and ensure the sensor is receiving power. Check the prongs on the oxygen sensor’s plug. If the resistance reads lower than the listed numbers in your repair manual, the sensor is damaged and requires replacement.
Why is the oxygen sensor on my car wearing out?
Your vehicle’s oxygen sensor measures the oxygen content in the exhaust, and adjusts engine parameters like the air-to-fuel ratio (AFR) to keep it running at its best. However, exhaust gasses are (by nature) hot and dirty, so the sensor can wear out with time.
